For me, Chrome has nothing Firefox don't have. Both have almost same set of features now . A year back, Chrome was in fact lagging in features. IMHO, the only difference i find is startup speed is better in chrome. But Firefox 4 nightly builds are rapidly catching up in that area. Load times for me are 5-10 seconds with a big Adblock list pre loading. Without Adblock list, it's a snap.
Both are rapidly catching up with each others features and so I don't find reason for me to switch to Chrome.
Firefox + Sync + Adblock + No Script + Awesome Bar is virtually unbeatable for me even though Chrome has equivalents.
